int Vect_delete_line	(	struct Map_info *	Map,
		int	line
	)

Delete feature.

Vector map must be opened on topo level 2.

This function calls G_fatal_error() on error.

Parameters

Map	pointer to vector map
line	feature id

Returns

0 on success

-1 on error

int Vect_restore_line	(	struct Map_info *	Map,
		int	line,
		long	offset
	)

Restore previously deleted feature.

Vector map must be opened on topo level 2.

This function calls G_fatal_error() on error.

Parameters

Map	pointer to vector map
line	feature id to be deleted

Returns

0 on success

-1 on error

int Vect_rewrite_line	(	struct Map_info *	Map,
		int	line,
		int	type,
		struct line_pnts *	points,
		struct line_cats *	cats
	)

Rewrites feature info at the given offset.

The number of points or cats or type may change. If necessary, the old feature is deleted and new is written.

This function calls G_fatal_error() on error.

Parameters

Map	pointer to vector map
line	feature id
type	feature type
points	feature geometry
cats	feature categories

Returns

new feature id

-1 on error

long Vect_write_line	(	struct Map_info *	Map,
		int	type,
		struct line_pnts *	points,
		struct line_cats *	cats
	)

Writes new feature to the end of file (table)

The function calls G_fatal_error() on error.

Parameters

Map	pointer to vector map
type	feature type
points	feature geometry
cats	feature categories

Returns

offset into file where the feature starts
